Try this:
int x = Int32.Parse(TextBoxD1.Text);
or better yet:
int x = 0; Int32.TryParse(TextBoxD1.Text, out x);
Also, since Int32.TryParse
returns a bool
you can use its return value to make decisions about the results of the parsing attempt:
int x = 0; if (Int32.TryParse(TextBoxD1.Text, out x)) { // you know that the parsing attempt // was successful }
If you are curious, the difference between Parse
and TryParse
is best summed up like this:
The TryParse method is like the Parse method, except the TryParse method does not throw an exception if the conversion fails. It eliminates the need to use exception handling to test for a FormatException in the event that s is invalid and cannot be successfully parsed. – MSDN
